Rear Differential (T-type)
DIFFERENTIALS
35) Install the drain plug.
NOTE:
Use a new gasket.
Tightening torque:
60 N·m (6.1 kg-m, 44.3 ft-lb)
36) Install the oil temperature sensor.
NOTE:
• Install the oil temperature sensor and the adapt-
er as a unit.
• After installing the rear differential assembly to
the vehicle, fill the gear oil, then use a new gasket,
and tighten to the specified torque. <Ref. to DI-16,
REPLACEMENT, Differential Gear Oil.>
E: INSPECTION
Wash all the disassembled parts clean, and exam-
ine them for wear, damage and other defects. Re-
pair or replace the defective parts as necessary.
1) Hypoid driven gear and drive pinion
• If there is evidently an abnormal tooth contact,
find out the cause and adjust until the teeth contact
correctly. Replace the gear if there is an excessive
worn or an incapable adjustment.
• If crack, cutout or seizure is found, replace the
parts as a set. Slight damage of some teeth can be
corrected by oil stone or the like.
2) Side gear and pinion mate gear (T-type (B1, B2))
• Replace if cracks, scoring or other defects are
evident on the tooth surface.
• Replace if thrust washer contact surface is worn
or scored. Slight damages of the surface can be
corrected by oil stones or equivalent.
3) Bearing
Replace if seizure, peeling, wear, rust, dragging
during rotation, noise or other defect is evident.
4) Thrust washer of side gear and pinion mate gear
(T-type (B1, B2))
Replace if seized, flawed, abnormally worn or hav-
ing other defects.
5) Oil seal
Replace if deformed or damaged, and at every dis-
assembling.
6) Differential carrier
Replace if the bearing bores are worn or damaged.
7) Differential case
Replace if sliding surfaces are abnormally worn,
burned, or cracked.
8) Companion flange
Replace if the oil seal lip contact surface shows
cracking.
9) Rear differential oil temperature sensor (T-type
(H5))
(1) Check that the rear differential oil tempera-
ture sensor has no deformation, cracks or other
damages.
(2) Immerse the rear differential oil temperature
sensor and a thermometer in water.
CAUTION:
Take care not to allow water to get into the rear
differential oil temperature sensor connector. If
water gets into the connector, completely re-
move any water inside.
